In a previous Enginursday, I showed off our MQTT tutorial using an ESP32 Thing and a Raspberry Pi. I mentioned at the end that you could use open source software such as Home Assistant to have your ESP32 control your house, and after many months the wait is finally over.

Using Home Assistant to Expand Your Home Automations

May 9, 2019

An introduction to Home Assistant, an open source home automation hub.

In this new tutorial, we load Home Assistant (specially on to a Raspberry Pi and get MQTT back up and running. Unlike the previous tutorial, with Home Assistant you can use much more than just MQTT. You can add Z-wave devices, smart thermostats like Nest, Amazon Alexa, Google Assistant and much more. By having control over both the hardware and software, you can use Home Assistant to create automations that are triggered from MQTT and control devices on other protocols. If you'd like to learn how to create a remote trigger switch over MQTT to control a WiFi plug, check out the tutorial linked above!

  • Thanks for the information, as I have HVAC system installed in my home which is fully controlled by just single remote.

  • I've got a mix of 8233s an esp32s running my house. See where I have weekly updates on items I've automated.

  • Thanks for the tutorial! Don't have time at the moment to read it in detail at the moment, (got back from a nearly 3 week "road trip" in the wee hours this morning) but did have time to glance through it, and also glance at the Home Assistant website, and was very pleased to find that they have support for both my old X-10 stuff and my iPhone (iOS), as well as DIY stuff (and LOTS of "off-the-shelf" stuff).
